Abstract
A windshield wiper assembly comprises a drive mechanism for at least one windshield wiper arm, together with a reservoir for a windshield washing liquid. The drive mechanism comprises a support structure, on which are mounted a motor and a linkage for transmission of motion between a spindle driven by the motor and at least one windshield wiper arm. The support structure is arranged to be secured on to the body of a vehicle, in particular an automotive vehicle. Pumping means are provided to project washing liquid from the reservoir on to the glass being wiped. The reservoir is so designed as to be accommodated substantially within the space envelope defined by the drive mechanism, and it is rigidly secured to the support structure of this mechanism so as to form an assembly therewith.
